Of course the government isn't trying to control our minds with fluoride
But I think it's safe to say that flouride should not be in our water, especially since you cannot regulate how much water a person drinks thus what amount of flouride they are consuming.
Also, you're right about using common sense and thinking critically about any situation. For me, too many things just don't add up with the 9/11 attack. For example, none of the 4 black boxes survived the attack yet they managed to salvage a paper passport from one of the terrorists. Or how about the Bin Laden family being immediately flown out of the country.
Then you have the issue with the insider trading on American Airlines stock.

Obviously, there are many other legitimate items as well as dead ends but perhaps the most interesting is Building 7, which was the third tower to fall that day in NY, something most people have never heard of. It's difficult to imagine how a steel structured building that was not stuck by any airplane could free fall 7 seconds into its own footprint.
